We developed a novel sputter process for deposition of amorphous layers from TiO2 with low defects levels for precision optics and photonics applications. The layer properties were investigated by XSEM, GIXRD, and particle measurements.

Optical Interference Coatings Conference (OIC) 2022.
To monitor complex thin film filter designs, multiple witness glass strategy is often required. We present a strategy of design division into sub-stacks in combination with mixed monitoring techniques to increase thin-film filter accuracy.

Optical monitoring of thin film interference filters is of primary importance for two main reasons: possible error compensation and greater thickness accuracy of the deposited layers compared to non-optical methods. For many designs, the latter reaso

Optical monitoring is a go to method for complex filters deposition; however, it can be easily shown that filter performance is dependent on monitoring strategy. When a non-quarter wave design needs to be deposited, usually one or minimal number of m

Variable filters, in which the bandpass central wavelength shifts along a dimension of the component, is a promising way to simplify and to miniaturize imaging spectrophotometer systems for spatial observation. In this paper, we present a new method
